A 2016 second-round pick, Slay earned three Pro Bowl nods during his first seven seasons with the Detroit Lions. He continued to play at a Pro Bowl level during his five seasons with the Eagles. Slay has 28 career interceptions, and his 160 career pass breakups is tops among active players.

The 34-year-old Slay joins a young defensive back group that includes third-year cornerback Joey Porter Jr. and Cory Trice, a rookie last season. The Steelers were in the market to add a cornerback or two after Donte Jackson, who led Pittsburgh with five interceptions in 2024, signed with the Los Angeles Chargers.

The Eagles took in the new league year by retooling their running back room. After Kenneth Gainwell agreed to terms with the Pittsburgh Steelers and the league year turned over Wednesday afternoon, the Eagles agreed to terms with former Green Bay Packers running back AJ Dillon according to a league source.
